Main characteristics：Main features: VG90 vertical gyroscope is a high-performance and low-cost inertial measurement device, which can measure the attitude parameters (pitch and roll), acceleration and angular velocity information of a moving carrier. The deviation of attitude and angular velocity is estimated by 6-state Kalman filter with appropriate gain, which is suitable for dynamic measurement of navigation and positioning.
Product Introduction
The VG90 vertical gyroscope product is a high-performance, low-cost inertial measurement device that can measure the attitude parameters (pitch and roll), acceleration, and angular velocity information of a moving carrier. The optimal estimation of attitude and angular velocity deviation is obtained through a 6-state Kalman filter with appropriate gain, which is suitable for dynamic measurement of navigation and positioning.
VG90 adopts high-quality and reliable MEMS accelerometers and gyroscopes, and ensures measurement accuracy through optimal algorithms. At the same time, the sealed design and strict process ensure that the product can accurately measure the motion parameters such as acceleration, angular velocity, and attitude of the carrier even in harsh environments.
Through various compensations such as nonlinear compensation, orthogonal compensation, temperature compensation, and drift compensation, the error sources of VG90 can be greatly eliminated, and the product accuracy level can be improved. VG90 has a digital interface that can be easily integrated into users' systems.
